Sweden was applauded for its pension and social care systems, although the report raised concern over growing wealth gap.

"In 1913, it introduced the world's first universal social pension scheme. The 100 year-celebration underlines that many years of development of social welfare is behind Sweden's ranking on the Index.

"About half of Sweden's elderly are members in one of the five national pensioners’ organisations. Over the years they have been strong advocates for the rights of older people.

"Indexes built on aggregated national data do not take into account economic, gender, social and other inequalities. At present pensioners’ organisations are concerned that the economic gap between pensioners and wage-earners is increasing. They strongly oppose the widening of this gap due to a tax system that puts higher taxes on income from pensions than on corresponding income from salaries.
